In this animated object, learners examine the hysteresis function of a sensor.
Single-Phase Motors: Introduction to Phase-Splitting
By Terry Bartelt, Terry Fleischman
Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
Interlocking Ladder Diagrams
By Terry Bartelt
Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.
Ohm's Law: Power
By Tim Tewalt, Patrick Hoppe
Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
Proportional Control Amplifier
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
Displacement Level Sensors
In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.
In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
By John Casey, Terry Bartelt
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
The Hydraulic Pressure Switch
This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.
Incremental Encoder Quadrature Modes
Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
